Title: Improvements in or relating to cold shaping of steel
IPC: B21C1/26
Filed: 1955-05-26
Abstract: 784,619. Making pistons and cylinders. AMERICAN RADIATOR & STANDARD SANITARY CORPORATION. May 26, 1955 [May 27, 1954], No. 15185/55. Classes 83 (2) and 83 (4). A method of producing elongate hollow articles which are provided with very smooth accurately dimensioned surfaces comprises cold extruding a hollow blank to the size and shape of the finished article and thereafter axially straightening said blank and smoothing out any irregularities on the surfaces thereof by a series of cold working operations comprising engaging one surface of the side wall of the blank with an axially straight tool so that the blank assumes the axial alignment of the tool and thereafter ironing out the opposite surface of the blank side wall by applying pressure thereto in excess of the elastic limit of the metal while the first surface is temporarily deformed by said tool to thereby bring said wall into permanent axial alignment with said tool and to permanently smooth out the irregularities in the surface thereof. In an embodiment a stress relieved low carbon or mild steel blank is subjected to a pickling operation, then washed and given a phosphate treatment and finally coated with lubricant in readiness for the sizing and surface finishing operation. Apparatus for carrying out the method comprises a punch shoe 16 on which is rotatably supported a ram plate 18 carrying four punches 24. The punch assembly moves towards and away from a die assembly mounted on a lower die shoe 28 provided with spaced die rings 30 (Fig. 6) for receiving the lower end of a blank 10 and a pair of die supports 34 each carrying a die ring 40. The assembly includes stripper heads 46 and mechanism (not shown) for rotatably indexing the ram plate 18 to successively position the punches 24 first over the die ring 30 and then over the die support 34. The punches are accurately machined 0.005 to 0.025 inch greater than the inner diameter of the blank. In operation on downward movement of the punch assembly a punch will engage within the bore of a blank seated in the die rings 30 and will expand the blank as shown in Fig. 8 and remove any irregularities from the bore. The punch assembly is then raised and the ram plate rotated to position the blanks and punches over the die rings 40. A second pair of blanks are then positioned in the die rings 30 and the punch assembly is again lowered. The first blanks are driven through the die rings 40 and any irregularities are removed from their outer surfaces by cold working and their inner surfaces are compressed against the punches thereby relieving the stresses set up by the elastic deformation and permanently deforming the metal. Finally, on raising of the punch assembly the formed blanks are stripped from the punches and the cycle is repeated with the second pair of blanks. The blanks may have a non-circular cross-section and tapering side walls. Specifications 718,506 and 718,590 are referred to.

Title: Improvements relating to apparatus for burning liquid fuel
IPC: F23D11/10
Filed: 1918-11-21
Abstract: 157,681. Kermode, J. J. Nov. 21, 1918. Spray burners.-In a liquid-fuel burner the fuel is supplied through a passage c' to the central bore b<5> of an inner barrel B, the flow of fuel being controlled by a valve C on a spindle c<4> operated by a handwheel c'. The valve spindle projects beyond the valve in the form of a twisted strip c<6> which imparts a whirling motion to the issuing fuel. Surrounding the barrel B is a casing A having on its underside a main inlet D through which air passes to the annular space a' between the barrel and the casing. On the upper side of the barrel is a port D' through which part of the air passes into the central fuel passage. The quantity of air passing through the annular space a<1> is controlled by a sleeve E which is adjustable on the screwed end a<6> of the casing A to vary the passage between the inner surface of the sleeve and a valve face b<3> on the end of the barrel. A dam F is arranged transversely acrcss the casing between the burner nozzle and the main air inlet to prevent any oil which drips from the nozzle from passing into the inlet. In one construction, Fig. 1, the valve facing b<3> never comes in contact with the inner surface of the sleeve E, and is formed on the end of a detachable sleeve b<6> which is mounted on the end of the barrel B and carries spiral blades b<4> for imparting to the air a rotation opposite in direction to that of the fuel. In another construction, the barrel B, Fig. 2, is formed integrally with the casing A, and the spiral blades b<4> are formed integrally with the barrel. The sleeve E may be formed with an inner valve surface e<1> which coacts with the valve facing b<3> formed on the end of the barrel, or the outer end of the sleeve may be flared, as shown in dotted lines. An indicator e<6>, working in conjunction with graduations on the sleeve E, enables the latter to be set in any desired position relatively to the casing A. Specification 154,238 is referred to.

Class 123(1) In a gravity feed device for maintaining a constant level of liquid in a receptacle M, for example for maintaining the oil level in an engine crankcase, the liquid flows into the receptacle through a pipe L from an air-tight supply tank A whenever the level in the receptacle falls below the pipe outlet and means are provided to prevent liquid from entering the receptacle when the tank is opened for refilling. The tank A has a conical member B disposed in its upper part below a hinged filling cover H, the member B having a filling orifice C normally closed by an airtight valve D which is held on its seat by a spring E. The valve is connected to cover H by a chain J and by means of its stem D' and a spring O to the stem N' of a valve N adapted to close the tank outlet orifice K but which is normally held off its seating by the action of gravity, the arrangement being such that the lifting of cover H to replenish the tank opens valve D to allow the liquid to enter the tank and at the same time closes the outlet valve N. To allow the level in tank A to be seen, the tank may be made of transparent material or it may be fitted with a transparent panel P. When the device is used to maintain the oil level in an engine crankcase, the pipe L may be connected to the upper end of a tubular dipstick having an outlet hole at the desired level
